The difference between the time avail-to do a job and the time required to do the job, is known as A. Event B. Float C. Duration D. Constraint

The correct answer is C. Float.

Float is the amount of time that a task can be delayed without delaying the project’s finish date. It is calculated by subtracting the task’s duration from the amount of time available to complete the task.

Event is a point in time at which something happens. It is represented by a node in a project network diagram.

Duration is the length of time required to complete a task. It is calculated by adding up the durations of all the activities that make up the task.

Constraint is a restriction that limits the options available to the project team. It can be imposed by the project’s scope, schedule, budget, or resources.
